KRELL KSA 50 100 150 0r 250.

Maybe you can bring your Bryston as well and put it into the syetm in place of the Krell, that could at least give you a benchmark. The Krell is superb at controlling a speaker, that was its greatest strength in its day (and why it was shown with Apogee speakers all the time), but your Bryston is no slouch there, so I'm not sure how much of a difference you'll hear. Of course, it has been a long time since I heard the old Krell. I would not recommend the 50s, though, it's a nice amp but, unlike the KSA 50 Mk II, is not far more powerful than its rating. But then again, what speakers are you driving? Do you really need all that control or power?

Hi Mike (Bigjoe),

How can you tell by looking at the cap and know if it is time to replace them? Thanks.

Ken.

Buy an amp made by Nelson Pass and forget this Krell nonsense. More musical, more reliable, more for your money.

I would look at the KSA 80b instead of the KSA 100. It is a newer design and has heatsinks instead of a fan. It can also be converted at the factory to mono if later on you wanted more power then it would become a KSA 160.

hi ken,you can see visable cracks in the caps & discoloration on the tops of them,you may even notice one of them starting to leak a little,just looking wont tell the whole story but if the amp has seen extreme use you will notice.
